Statistical mechanical methods of equilibrium have been used to evaluate the tension of a polymeric chain and then of polymeric chains that are jointed together with permanent junctions, by considering the free energy of the system. The tension is shown to increase when there exist junctions, i.e. when the motion of a chain depends on the motion of other chains. This is also an experimental fact. The dependence of the tension on the position of the junction points has been studied and also the dependence of this tension on the number of molecular units of the macromolecule. The result has been compared to that for the macromolecules without junctions.
